摘　　要：水泥厂等高耗能工业负荷用电量大、改造成本低,具备相当可观的调节潜力,但其复杂的工艺要求与严格的过程约束限制了企业参与需求响应的积极性。为此,文中提出一种需求响应下计及水泥厂负荷生产流程的经济调度模型。首先,基于最新发布的需求侧市场化响应电价政策提出价格和激励联合需求响应策略,挖掘长期削峰填谷和短时供需不平衡混杂场景下负荷侧可调潜力。然后,分析水泥厂的典型生产过程,利用状态任务网方法刻画各生产环节的耦合关系,提出生产流程约束以保障功率调节过程中的生产安全,构建面向需求响应的水泥生产流程经济调度模型,为水泥厂制定经济性最优的安全生产计划。最后,基于水泥厂生产数据进行算例仿真分析。结果表明,所提模型能够在保障工业企业生产安全的前提下,降低其综合用电成本,提升企业参与需求响应积极性,实现企业生产用电需求与网侧调度需求的兼顾。Energy-intensive industrial loads,such as cement plants,have considerable potential for adjustment due to their high power consumption and low transformation costs,but their complex process requirements and strict process constraints limit the enthusiasm of enterprises to participate in demand response.Therefore,this paper proposes an economic dispatch model considering the production process of the cement plant under demand response.Firstly,based on the latest demand-side marketoriented response electricity price policy,a joint price and incentive demand response strategy is proposed,and the potential of load-side adjustment under mixed scenarios with long-term peak shaving and valley filling and short-term supply-demand imbalance is explored.Then,the typical production process of the cement plant is analyzed.The coupling relationship of each production link is described by using the state-task network method.The production process constraints are proposed to ensure the production safety in the process of power regulation.The economic dispatch model of the cement production process oriented to demand response is constructed,and the most economical safety production plan is formulated for the cement plant.Finally,based on the production data of the cement plant,the simulation case analysis shows that the proposed model can reduce the comprehensive electricity cost of industrial enterprises on the premise of ensuring their production safety,improve the enthusiasm of enterprises to participate in demand response,and realize the balance between the production power demand of enterprises and the needs of gridside dispatch.
